Abstract

The invention relates to an arrangement for damping a pulsation of a fluid conveyed through a conveying device, the fluid being led by way of a first tubular element into a cavity formed by a flexible element and emerging from the cavity by way of a second tubular element, and the tubular elements (23, 25) being arranged within the cavity in the flexible element.
There is provision for the length (a, b) of the individual tubular elements (23, 25) to be smaller than the length (c) of the cavity and for the sum of the lengths (a + b) of the tubular elements (23, 25) to be greater than the length (c) of the cavity.
